Zamia roezlii (chigua[1]) is a species of cycad, a palm-like pachycaulous plant in the family Zamiaceae. It is found in Colombia (Choco, Nariño, Valle del Cauca, and Amazonas departments) and the Pacific coast of Ecuador. It is named for the Czech botanist Benedikt Roezl. A single sperm cell from Zamia roezlii is about 0.4mm in length and is visible to the unaided eye, being the world's largest plant sperm cell. Drosophila bifurca, a species of fruit fly, has sperm that are 5.8cm long, albeit mostly coiled tail.[2] The tree is up to 22 feet (seven meters) in height with fronds up to 100NaN0 long bearing leaflets up to 200NaN0 long and 6inches wide.[3]
